Please note
Only in this way is the Checkbox ready to operate:
·
Leave non−used sensor inputs open.
Otherwise the display will show the operating status Full",
although the buffer zone is free. All good parts will be re
turned. The small parts conveyor will be switched off after
30 s (standard setting).
Signal duration In order to avoid unnecessary switching movements, the
Checkbox reacts only after a certain signal duration to the
sensor signals for Buffer zone full" and Buffer zone empty."
